Modeling Your Design

Avoid Unaccelerated Primitives

VCS cannot accelerate tranif1, tranif0, rtranif1, rtranif0, tran, and rtran

switches. They are defined in IEEE Std 1364-2001 page 86.

Avoid Calls to User-defined Tasks or Functions Declared in

Another Module

VCS cannot accelerate user-defined tasks or functions declared in

another module. For example:

module bottom (x,y);

always @ y

top.task_indentifier(y,rb);

endmodule

Avoid Strength Specifications in Continuous Assignment

Statements

Omit strength specifications in continuous assignment statements.

For example:

assign net1 = flag1;

Simulates faster than:

assign (strong1, pull0) net1= flag1;

Continuous assignment statements are described on IEEE

1364-2001 pages 69-70.
